Users can now search for songs by humming, singing, or playing them.

The app is getting a new "You" tab combining account info, watch history, playlists, etc.

Videos will highlight "Like and Subscribe" buttons when creators say those phrases.

Other new features include rotating top comments, live view counts in first 24 hours, and a revamped video description menu.
